Tablet on Amiga

[Ponos2D]

I bought Aiptek8000U USB tablet!

It works on Spider with Poseidon but it does not work as it should! It works just like mouse and that is not good for drawing in paint program like TVPaint! I can't draw good circles and curves.
I installed tablet on my sisters PC, and there works GREAT! When I draw circle, it is circle. Pointer is placed on monitor, exactly the same place where you move pen on tablet. Margines of tablet drawing area are actually edges of monitor screen!
Is it possible to make tablet work like this on Amiga?

Thanks
